Hi!
I know what the manual says.. 10w30 in summer, 5w30 in the winter. But lots of people are using 10w40, or 15w40. Some even 0w40, and reporting great results.
I currently have 10w40 (bought it like this), and I find the oil pressures a bit high when cold and a bit low when hot, so I can imagine that a w30 oil (that toyota recommends) would only worsen the hot pressure. As for the cold pressures I guess 0w or 5w would be better.
I'm leaning towards a 0w40 oil..
Any thoughts?
